Sorry I mistakenly posted the wrong question. I will post the correct question. I really appreciate all of your help! You make physics same less foreign to me. Again thanks!

Can you please explain how you get to x=0.707q. I got how you got up to -q+sgrt2*X=0 but i keep coming up with a different answer than 0.707q.

The answer 0.707q is correct but I am still not understanding how to get to that answer. I have another problem just like this one but with different values for q. When I use the formula above I am coming up with an incorrect answer. Please help. My question is: A charge of +1q is fixed to one corner of a square, while a charge of -3q is fixed to the diagonally opposite corner. Expressed in terms of q, what charge should be fixed to the center of the square, so the potential is zero at each of the two empty corners?

Please tell me where I went wrong. R= V^2/power R= 120V^2/2.00x10^2 R= 72 Resistance = restivity x delta Length/ area 72 = (100x10^-8)(delta length/ pi r^2) 72 = 9100x10^-8) (delta length/ 0.000002011) 72 - (100x10^-8)*(0.000002011) = deltaL 0.000144792 = delta Length

I am so confused! Can you please define "cross product". I interpret it to mean that you multiply the value of V and B. Obviously this is incorrect. Will my answer have a negative value because of the mass of the electron? This is what I did: Acceleration = [(q V X B)/ m (-1.60x10^-19)(6.789932x10^12)(X)(5.00x10^-5)] / 9.11x10^-31) I got the value of V from the equation for KE KE = 1/2m V^2 2.10x10^-5 J = 1/2(9.11x10^-31)V^2 (2.10x10^-5)/(4.555x10^-31) = V^2 4.610318x10^25 = V^2 6.789932x10^12 = V

Thank you so very much. It is only because of you and drwls that I am passing my physics class. Thanks again.

Please clarify.

To do this problem you need to know is that 1 yd = 36 inches.

Convert 5/8 and 3/4 to a decimal. This will make it easier for you to see the answer.

Again, convert the fraction part of the question to a decimal and add them all together.

I got 114.5 ft. per second. Is this right or wrong?

Thanks!

I think I am missing it. How do I get the change in time.

45 goes into 120 2 times.

about 4

so the answer is 4. thanx!!! ur a big help!! went through it step by step.

ok i see.i was'nt sure what the opposite of b^2 would be. thesquare root of 900 is 30. the distance from Carla's house to the flowers is 30 meters.

a^2. does that mean squared??

(40)^2 + b^2 = (50)^2 1600 + b^2 = 2500 -1600 -1600 b^2 = 900 im not sure wat the next step is

so that means 10^-2 is 0.001?

ok i see. im still not sure exactly how u figured out the answer.is there another way to explain?

much better!!!! i think i get it now!

All I need is a function rule. For example, y= 1/2x + -1

I just need a function rule for the graph. ex. y=2x+1

This does not help me at all. I am only in the beginning of Algebra 1. I have had nothing yet about parabola or the symbols you use. I just need a function rule for a graph!!!

I am sorry but you are mistaken. This is the first time I have been on this website in about 3 weeks. I have posted the question just above this one as well and another one just a minute ago for you to check my working. I will make an educated guess and repost the question.

As I said in the previous post, you are mistaking me for someone else. Maybe there is someone in my class who is also using this website. You and drwls have been helping me with my physics homework since the spring semester and I know better not to pretend to be someone else. I will make an educated guess and repost this question.

Your response confuses me. Please clarify.

Thanks! Did you see my response to your comment on my two earlier questions?

My 8:19pm and 8:21 post

52 M&M's per package package weight .1034lb I have to use a factor equation to get the answer and I do not know how?

it is a four sided where 16 is replaced by c=24 and d=20,e=24,f=28. It goes and on and ask to find the unknown side lenghts if c=24. Each measure is in centimeter. Express your answers in decimals. That is the whole question.

This on is pretty easy, you just have to create 2 equations base on the problem. X = Jonh Y = Brenda X+8 =Y Y+8 =X X=Y-8 Y+8=2(Y-8) Y+8=2Y-16 Y-2Y=-16-8 -Y=-24 Y=-24/-1 Y=24 X=Y-8 X=24-8 X=16 I also post the answer to your other problem... hope that help you at least a little.

Thank you Ms. Sue. This was an extremely big help! Happy Holidays. M.J.

Thanks!

Thank you!

Please help on my question!

Thank you, anyone who helps!

I really appreciate any opinions!

Thank you.

Oh, then the answer is 100. Thank you.

I still don't quite understand.

Thanks so much for the help, I didn't even consider what you mentioned! Again, I really appreciate it!

I understand now. When i divided it gave me .047. Thank you for your help.

I thought you take 10^9-5 or 10^4 is the exponent

answer=4.7 x10^3

I divided 1.4 x 10^9/3.0 x10^5= 4.7 x 10^4 sec

thanks

I make guys have to pee And girls comb their hair. I make celebrities look stupid And normal people look like celebrities. I turn pancakes brown And make your champane bubble. If you sqeeze me, I'll pop. If you look at me, you'll pop.

I replotted the points and found the coordinate of T= (-5,10)

None have been discussed.

I'm sorry about the mix up. The question is: What are the services (social and health) that might be needed by the mentally ill? Thanks

This helps me a great deal to construct my response. Thank you Ms. sue!

Thank you for your brilliant input Jamie!!

DrBOB222 - So, if I have cation data for Surface water and groundwater...how do I plot the data to see if I have cation exchange going on. Would I just begin plotting any given cation on the x-axis and another cation on the y-axis and then what...what would the graph look like if there was exchange happening. I guess I am trying to find out if these waters (surface water and shallow groundwater) are coming into contact at all (i.e., mixing).

but the rule of 5%? 0,0100/(1.00x10^-4) =100% The aproximation you do is not valid...or? Ka= (1,0*10^(-4))^2/(x-1*10^(-4) )=1,00*10^(-6)....I got c=0,0101M :-(

8)4 9)2 10)3 11)1 12)3 13)2 14)1 15)4 16)3 17)2 18)3 19)3 20)3

We did the theme "community workers" already.... in this theme the children talked about different community helpers such as the firefighters, doctors, etc....

Thanks for your suggestion, but remember this is pre-k (most of the children recently turned 3).... wont this be a bit too complex?

I think I've got it, thank you!

Hi! Thank you so much for your answer! according to my calculations...I got: 1 bar = 750 mm Hg = 0.986 atm. At constant T and P, volume and moles are proportional, so volume percent = mole %. Pa = (xa)(Pt) , , ,the partial pressure of "a" is equal to the mole fraction of "a" times the total pressure. (mole fraction = %) P CO = (0.002)(0.986) = 0.00197 atm P O2 = (0.03)(0.986) = 0.0296 atm P CO2 = (0.12)(0.986) = 0.118 atm Qp = (P CO)^2 (P O2) / (P CO2)^2 = (0.00197)^2 (0.0296) / (0.118)^2 = 8.3 x 10^-6 which is much greater than Kp = 1 x 10^-13. Since Qp > Kp, the reaction will go back to the left (make more CO2). Adding a catalyst does not change the amount of CO produced, only how fast it is produced. Is that correct?

I think that if steps are not taken at an early age to correct behavior problems, then the adolsenct is destined to countuine into a patter of criminal behiours. I think that as the adolesent travels down this path of devient behaviors each act will countine to increase in severeity. Am I on the right track?

I need to find an recent news article about an adolescent offender to I can describe the devlopment of the offender's behavior, and suggest changes to keep the adolescent from becoming an adult offender. I can not find any articels that are recent other that school shootings. Any suggestions????

so i did... 5n+10(2n)+750-75n=550 5n+20n-75n=-200 -50n=-200 n=4 four nickels eight dimes 12 quarters .. that's not right! D:

ohh! for some reason i multiplied 4 and three to get 12 quarters.. wow silly mistake! thanks so much for the help!!

you could write something about the paparazzi being all over them and all of the glamour that surrounds their lives. ....or you could just say that people don't have lives of their own and decide to feed of celebrities.

You are a board member of your homeowners association. at your next meeting your goal is to educate other homeowners about energy conservation. Review the follow energy resource plan outline: introduction, renewable vs nonrenewable, Methods to conserve and help the environment, governments efforts, conclusion can you offer any help.

I am also taking this class and had this same assignment. It was difficult to write the essay part of it too, without grouping people together. I really think it did make sense to do it.

That is what I thought, but I wasn't sure. Wouldn't the amount of water vapor in the air vary at different times throughout the year and depend on location, the time of year and the air temperature (among other factors)? But overall it is fairly constant? Thanks again!

So far I have: IX - (the cardinal number that is the sum of eight and one) TUSI - (The Tusi-couple is a mathematical device in which a small circle rotates inside a larger circle twice the radius of the smaller circle. Rotations of the circles cause a point on the circumference of the smaller circle to oscillate back and forth in linear motion along a diameter of the larger circle.) This leaves the letters ZZSPPJ to fit into the first word MA??E?A?I??.

Sorry I mis interpret the question. I assume: Z = M A = A S =T M = H E = E I = I X = C P = S U = U J = Q T = S Which gives you MATHEMATICS IS QUSI I tried I hope it is right.

Can someone check me on this please. the formula is: 1/d1 = (1/f)-(1/d0) where d1 = image distance f = focal length of the mirror(object height) d0 = object distance from the mirror giving you: 1/d1 = (1/15mm) - (1/5mm) 1/d1 = -0.1333333 recurring take the inverse of this number giving: d1(image distance) = -0.1333333^-1 d1(image distance) = -7.5mm

I agree, probably because of the genes , as you know it is a different development in the stage of pregnancy. Better off the doctor should know!

so would I = ma^2? i am confused

okay no i was lost but thank you i will go check it out.

Thank you so much!!!

what I'm not in 3rd grade I'm in 7th

what the damn guestion?

which angles are you confused about?

The course i am taking is Advanced Mathematical Concepts/Precalculus with Applications. Thank for your help.

I thought so. Thanks

thank you

No because all prime numbers besides 2 are odd

Thankyou DRWLS

To estimate you must look at the numbers after the decimal point. In the first number the tenths place is 7. When you estimate you must look at the number to the right. The number to the rightof the 7 is 1. Since 1 is smaller than 5 you make the number 7. If the number to the right was 5 or bigger you would round it to 8. to round 5.891 you woulmake it 5.9. Now the problem becomes 9.7-5.9 I Hope I helped!
